Sample Flashcards

Reflecting in y = x

Swap x and y coordinates. Example: (3,4) → (4,3)

Reflecting in y = -x

Swap coordinates AND change both signs. (x,y) → (-y,-x). Example: (3,4) → (-4,-3)

Sample Questions

A point P has coordinates (3, 5). It is reflected in the x-axis. What are the coordinates of its image P'?

A. (−3, 5)
B. (3, −5)
C. (5, 3)
D. (−3, −5)
